LUBRIGATOR.

Specification of Letters Patent.

Patented Nov. 15, 1910.

To all whom it may concern:

Be it known that I, FREDERIO CHARLES voN HAXTHAUSEN, a subject of theCzar of Russia, and resident of St. Petersburg, Russia, have invented acertain new and useful Improvement in Lubricators, of which thefollowing is a specification.

This invention relates to improvements i lubricators and consists incertain features of construction as hereinafter more particularlydescribed.

The invention is shown in the accompanying drawing in which likereference letters indicate like parts, and in which Figure 1 is asectional elevation of one embodiment of the invention; while Fig. 2shows a modified construction.

In the interior of the container 2 which is adapted to be closed by thecap 3 (Fig. 1) is a float 1 having a central opening 14 for the passageof the outlet pipe 15, having a discharge end 13 through which the oilflows. To this float is connected a siphon the adjustable limb 4 ofwhich projects into the pipe 15 while the other limb 5 is rigidlyconnected with the float 1. It is clear that by adjustment of the limb 4the distance between the open ends of the limbs and thereby the siphonicaction can be increased or diminished. The open end of the limb 5 isformed as a valve seat which is protected from impurities by a gauze 7,and is controlled by a valve 8 mounted on a rod 9 which can be adjustedby a screw 16 to correspond to the viscosity of the oil. The rod 9 isformed of a material having a high coefficient of expansion so that onthe temperature rising the valve 8 closes the limb 5 more and more inorder to keep the flow of oil constant as the viscosity decreases. Anair escape opening 12 may be provided and the same may be closed by ascrew 11, as clearly shown in Fig. 1.

In the construction shown in Fig. 2 the limb 5 projects into a suitableopening 17 in the float 1. At the lower end of said opening 17, thefloat carries a support 20 on which a filter screen 21 is mounted andwhich, as shown, projects somewhat into the opening 17. In thisconstruction the limbs 4; and 5 are made integral and the limb 4:

projects/into the pipe 15 loosely, and the limb 5 is provided with a lug19 with which a rod 18 hasthreaded connection. The rod 18 is revolublyconnected with the float l and is provided with a thumb screw so thatwhen the rod 18 is adjusted a relative change of the position of thefloat 1 with respect to the lower ends of the limbs 4 and 5 will result.It will be seen from the foregoing that the opening 17 is designedtoform an extension of the limb 5 so that when the float 1 is adjusteddownwardly the limb 5 will be lengthened and when the float 1 isadjusted upwardly the limb 5 will be shortened. It will thus be seenthat the siphonic action can be increased or decreased by thisadjustment of the float with respect to the limb 5'. In thisconstruction the regulation of the passage to correspond to diflerenttemperatures is preferably eflected by a valve 22 actuated by a rod 23of high coeflicient of expansion which on the temperature rising closesmore or less of the opening 24 in the limb 4 which is formed as a valveseat. The adjustment of this valve 22 to correspond to the varyingviscosity of the oil is effected by a set screw 25.

When the lubricator is first started the container 2 is completelyfilled with oil, the screw 16 (Fig. 1) or 25 (Fig. 2) is un screwed andthe float pressed to the bottom of the container so that the siphon iscompletely under oil. After the tubes are filled with oil and all theair expelled, the screw 16 or 25 is screwed on again, and the cook 10opened so that the siphon commences to act and the float which is nowreleased rises to the surface.

Having now described my invention what I claim and desire to secure byLetters Patent of the United States is 1. In a lubricator adapted todeliver 111- bricant continuously, the combination with a lubricantcontainer of an outlet tube, a float movable in the container, anadjustable siphon having one limb connected to the float and the otherguided in the outlet tube, a valve for controlling the outflow, and athermostatic device for regulating the position of the valve.
